I don't think you can get a replacement unless you can pick up one off Gumtree/Ebay. I had a couple that I sold a year or so ago. Only other thing is to get it welded up and that isn't going to be easy to get somebody to do it as it has to be set up in a lathe to get it true. I still have one here but it has the bolt on wheels, but as is always the case postage makes things prohibitive these days
